Abstract: A method and apparatus for loading an XML document into memory is provided. A  client loads one or more array elements into a first partition of an array that is maintained in memory. Each array element represents an XML element of an XML document. Upon determining that an amount of data maintained in the first partition exceeds a first threshold, the client subsequently loads array elements into a new partition of the array. Upon determining that an amount of data maintained in the memory of the client exceeds a second threshold, the array elements of the least recently used partition are persistently stored in a database without persistently storing the entire XML document. When the last XML element of the XML document is loaded into a partition of the array, that partition is persistently stored in the database, thereby causing the entire XML document to be stored in the database.

Title: Method and apparatus for selecting a transport format combination
Inventor: ZHANG GUODONG
IPC: H04L12/56
Filed: 2006-12-12
Abstract: A method and apparatus for selecting a transport format combination (TFC) are disclosed. A TFC recovery and elimination unit generates an allowed transport format combination set (TFCS) subset by recovering supported TFCs and eliminating not supported TFCs based on allocated radio resources and parameters that are new. A multiplexing and transmission sequence number (TSN) setting unit generates a medium access control (MAC) protocol data unit (PDU) by multiplexing at least one higher layer PDU within a maximum supported MAC PDU size. A TFC selection and padding unit selects a TFC for the MAC PDU from the allowed TFCS subset and performs padding of the MAC PDU, if necessary, so that the MAC PDU fits into the selected TFC.  For retransmission, a new allowed TFCS subset may be generated based on new radio resources and parameters and the MAC PDU  may be fragmented.

Title: Enhanced lng regas
Inventor: VAN WIJNGAARDEN WIM
IPC: F17C5/06
Filed: 2006-11-30
Abstract: Liquefied hydrocarbon gas carried by a tanker (78) is transferred to an import terminal (10) where the liquefied gas is heated to vaporize it and to heat the cold gas to at least -30°C but preferably about 0°C, with the warmed gas transferred to a gas receiving facility (20, 83). Vaporizing and heating is accomplished by using a large number (more than 10) of vertically mounted air vaporizers (84) of a known type, which use environmental air that flows down the exterior of the finned tubes in which the liquefied or cold gas flows. In the present invention a large number of individual vaporizers are positioned in close proximity to each other, i.e. within a distance that is smaller than half the vertical height of the vaporizer tubes. Their close proximity allows many units to be installed on a small plot space, and also affects their thermal performance.

Abstract: An apparatus for extracting liquid from a biomass material for removal or recovery by compaction uses an auger with multiple flights within a barrel to compress the biomass material such as straw, sawdust, or flax waste which can contain up to 50% liquid content through a discharge end of the barrel. The material is forced by inclined tips on the end of the auger flights into a polygonal forming barrel which includes a slotted section such that the liquid content is released from the material under the high temperature and pressure generated by the auger through the slots. This way, the machine uses the same mechanical process to both compact and dry out the biomass material, thereby reducing or eliminating the need to dry the biomass material in a separate prior process.

IPC: H04B7/06
Filed: 2007-03-26
Abstract: Techniques for efficiently sending channel state information using differential encoding are described. Differential encoding may be performed across space, across frequency, across space and frequency, across space, frequency and time, or across some other combination of dimensions. In one design, spatial state information may be determined for multiple spatial channels on multiple subbands. The spatial channels may correspond to different antennas, different precoding vectors, etc. Channel quality indicator (CQI) values may be obtained for the multiple spatial channels on the multiple subbands. The CQI values may be differentially encoded across the multiple spatial channels and the multiple subbands to obtain differential CQI information. In another design, CQI values may be obtained for multiple spatial channels on the multiple subbands in multiple time intervals and may be differentially encoded across space, frequency and time. The differential CQI information and the spatial state information may be sent as feedback.

Title: Power interrupt management for an aircraft electric brake system
Inventor: GRIFFITH TODD T
IPC: B60T8/17
Filed: 2007-08-24
Abstract: An electric brake system (100) for an aircraft as described herein electrically actuates brake mechanisms (108) in a seamless manner when a power interrupt condition is experienced. While operating in an autobraking mode and in response to a power interrupt condition, the electric brake system (100) preserves the last brake actuation command generated by the autobrake function. After normal operating power is reestablished, the last brake actuation command is retrieved and processed by the electric brake system (100). While operating in a pedal braking mode and in response to a power interrupt condition, the electric brake system (100) discards the last brake actuation command generated from brake pedal interaction. After normal operating power is reestablished, the brake pedal data is refreshed to generate a new brake actuation command. These procedures reduce lurching and unexpected brake actuation levels following a power interrupt in the electric brake system (100).
